Question 1

Know the processing of DDGS

Answer 1

• Ethanol is being produced to reduce dependence on petroleum products.
• Ethanol-gasoline blends reduce air pollution from automobile emissions.
• Co-product of the distillery industries
• 98% originates from ethanol
• 1-2% comes from alcohol beverage industry
• In 2013, approximately 44.0 million tons were produced.

Question 2

Know the processing of DDGS

Answer 2

• Co-product from ethanol production via dry milling
• Ethanol production requires only starch from corn.
• Protein, fiber, and oil are by-products used to make DDG/S.

Question 3

Understand the differences in phosphorus and calcium sources used in poultry production.

Answer 3

Phosphorus Sources

• Dicalcium phosphate
• Defluorinated phosphate
• Dicalcium phosphate is higher in phosphate availability but defluorinated phosphate improves pelleting throughput by polishing pellet dies.
• Defluorinated phosphate is used more by the broiler industry.

Question 4

Understand the differences in phosphorus and calcium sources used in poultry production.

Answer 4

Calcium Sources

• Fine limestone
• Coarse limestone
• Oyster shell
• Layer industry uses the coarse limestone because the larger particles release calcium slower, which is needed for egg shell production.
